I think those suggestions refer to useing dyndns.com, which is a
service that essentially sets up your name so it only can be resolved
by their dns servers(points the rest of the worlds servers at theirs
for authoritative answers), all made to work in pretty close to
realtime by having you 'put me online' script grab the ip address
your are given and forwarding it to dyndns, at which point your name
will resolve, albeit a second or so slower due to the indirection
involved.
